• I2C

  Inter-Integrated Circuit

• SPI

  Serial Peripheral Interface

• SWI

  Single Wire Interface (Atmel)

• CAN

  Controller Area Network

• HDLC

  High-level Data Link Control

• HDMI CEC

  High-Definition Multimedia Interface Consumer Electronics Control

• I2S

  Inter-IC Sound

• PCM

  Pulse-Code Modulation

• JTAG

  Joint Test Action Group

• LIN

• SMBus

  System Management Bus

• SWD

  Serial Wire Debug

• UNI/O

• USB LS/FS

  Universal Serial Bus Low Speed / Full Speed

• Baud rate

  data rate measured in bits per second

• MSB

  most significant bit

• LSB

  least significant bit

• Parity

  additional information added to the data to provide error detection information

• Processing backlog

  In the Saleae software, the data recorded from the device is transformed to the storage format as it is recorded, in near-real time. If the process is unable to keep up with the recording in real time, the processing backlog will grow as unprocessed data are buffered.

• Trigger backlog

  In the Saleae software, when the trigger is used, the processed data are then fed into the trigger in near real-time. If the trigger thread is unable to process the already transformed data in real time, the trigger backlog will grow as processed (but not yet searched) data are buffered.

• MHz (Megahertz)

  Millions of cycles per second. It is a measure of frequency, usually in reference to bandwidth.

• Protocol Analyzer

  A software plugin for the Saleae software that will decode standardized signals into bytes.
